Application led June 18, 1915. Serial No. 34,810.

To all whom it may concern:

Beit known that I, GEORGE'B. KOHLER, a citizen of the United States, and a resident of the city and county of Philadelphia,

- so as to close an electric circuit at one place by means of a device which may be operated from any of several places in the car, so that under no circumstances will a passenger be exposed to an electric shock, while energizing the signal. This object is accomplished by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is an interior view looking outwardly showing a portion of a car provided with my improvement; Fig. 2 is a sectional view, taken on the line 2 2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a sectional view, taken substantially on the line 3 3 of Fig. 1, looking in the direction of the arrows; and Figs. 4, and 6 are sectional views taken substantially on the lines 4 4, 5 5, and 6 6 respectively, of Fig. 1, looking in the direction of the arrows.

Throughout the various views of the drawings,y similar reference characters designate similar parts.

. My improved circuit closing device 1 is provided with a suitable shaft 2 mounted near the tops of the stanchions on `one side ofa car, the structure being duplicated on the other side, each shaft 2 being mounted so as to turn in suitable brackets 3 which are secured in each car adjacent to the curtain rollers, not shown. They may be mounted in any suitable way, as by screws, as shown in dotted lines. Each shaft 2 carries a number of depending arms 4'.l each of which is adjustably secured' by means of ears 5 and a screw 6. Each arm ,4 runs downwardly adjacent to* a stanchion 7 and within the lining 8 on the interior of the Vcar to a suitable push button 9 mounted in said lining with its inner end adapted to connect the lower end of the arm 4 so that when the button 9 is pressed inwardly, the shaft 2 is shifted; about-its axis through a few degrees. v

In addition to the arms 4 above described, eaclrshaft 2 carries a similar arm 10 with ears 5 adapted to be united by a screw 6, and the upper of these ears is adapted to engage a rubber cushion 11 secured to an)7 convenient part of the car, so as to cushion the return movement of the arm and prevent all undue noise or vibra tion. The upper part of the arm 10 extends horizontally and then it is bent vertically at right angles and runs substantially parallel to the stanchions 7 to a push button 12 which ispressed by a suitable spring, not shown, against the lower end of this arm 10, and vthis push button is secured in a suitable casing 13," which has two? wires 14 and 15 respectively that run to the buzzer or bell (not shown) which is located at .any convenient part of the car, so that when the push button 12 is pressed by the arm 10 a circuit may be closed, and when the pressure is removed the circuit will be open, as is common in push butto-ns of this character. The casing 13 may be mounted in any suitable way, and is preferably'mounted in a suitable bracket 16 which connects the stanchions 7, or it may be mounted in any other suitable way.

In view of the foregoing, the operation of my circuit closing device'I will be readily understood. When any of the buttons 9 are pressed the arms 4 are swung on their pivot which is the axis of the shaft 2. and

this shaft is slightly shifted so as to cause the arm 10 to press against the button 12 and close the circuit. When the pressure is removed from the button 9 the spring tension on the button 12 forces it against the arm 10 thereby restoring the shaft 2, and all parts connected therewith, to their normal positions.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures which come within the scope of the annexed claims.

Having thus described my invention, what I claim.; is:

1. In a device of the class described, a shaft and means for mounting the same so that it may rotate about its axis, arms fastened to said shaft, a push button, adapted to close `a circuit, operated byl one of said arms, and a push button adapted to opera-te another arm when pressed by an operator.

2. n a device of the class described, a shaft adapted to be shifted about its axis and means for mounting the same, arms secured to said shaft between its ends and extending downwardly therefrom in the car post casings, the end of one of said arms operating a circuit closing device and the end of the other of said. arms being operated by a. push button.

3. In a device of the class described, a rotatable shaft extending substantially@ the length of a car, a plurality ofl arms disposed in the car post casings and secured to the shaft, circuit closing devicesoperated by the said arms and push buttons for engaging the lower ends of said arms.

4. In a device of the class described, a horizontally extending rotatable shaft ex- Gopies of this patent may be obtained for tending substantially the length ofa car,

an arm Within a car post Vcasing having its upper end rigidly secured to said shaft. and its lower. end engaged byv a manually operated push button, another arm within another car post'casing having its upper end rigidly secured to said shaftV and its lower end engaging circuit closing means.

5. In a device of the class described, a shaft adapted t0 Vbe shifted about its axis, a mounting for said sha-ft, an arm having an offset. upper end secured to saidk shaft and its lower end engaging a Inan'ualb7 operated push button, another arm extending downwardly at right angles to the shaft, having an offset upper end secured to the shaft and its lower end engaging circuit closing means.

Signed at the city and county of Philadelphia,I and State of Pennsylvania, this 11th day of June, 1915.
